Introduction to SNMP and Its Configuration in Linux Servers
SNMP is a management protocol that is used to monitor network-attached devices for faults and performance issues. SNMP agents can be installed on most devices that are running a Unix or Linux operating system.

In this guide, we will show you how to install and configure SNMP agents on two different Linux servers. We will also show you how to install and configure an On-Premise Poller to monitor your servers.
Why Configuring SNMP Is Important
You may be wondering why configuring SNMP is so important. After all, doesn't monitoring your server's agentless work just fine?
Well, not really. Agentless monitoring is great for checking on the status of your servers and getting alerts when something goes wrong. But it doesn't give you the level of detail you need to troubleshoot issues.

That's where SNMP comes in. When you configure SNMP agents on your servers, you can get reports on things like CPU usage, memory usage, and disk space. This gives you the information you need to proactively address any potential problems before they become a bigger issue.
How to Configure SNMP in Linux Servers
First, make sure you have the SNMP package installed on your server. To accomplish this, issue the following command:
# yum install SNMP
Once you have the package installed, you need to configure it. You can do this by editing the file /etc/SNMP/SNMP.conf.
In this file, you need to specify the community string and the location of your MIB files. The community string is a password-like string that allows access to your SNMP agent. The MIB files contain information about the objects that you want to monitor.
You can find more information about configuring SNMP in Linux servers in the official Red Hat documentation.
How to Install and Configure SNMP Agents
Let's walk through the steps of installing and configuring SNMP agents on a Linux server.
First, you need to download the SNMP agent software. There are a few different options here, so you can choose the one that best meets your needs.
Then, you'll need to configure the agent. This involves specifying the hostname or IP address of the server you want to monitor, and then the community string, which is a password used for authentication.
Once the agent is configured, you can install an On-Premise Poller. This is what will allow you to see your server data in On-Premise Manager.
And that's it! You're now ready to start monitoring your Linux servers agentless, with the support of SNMP.
How to Install an on-Premise Poller
You can install an on-Premise Poller to monitor your Linux servers agentless. The Poller will query SNMP Agents on the target systems and collect performance data. This data can then be viewed in the SolarWinds Server & Application Monitor interface.
To install an on-Premise Poller, you need to have a machine that meets the following requirements:
- either Windows Server 2012 or 2016 ( 64-bit)
- 2GB RAM
- goog_210676230950GB disk space

Conclusion
In conclusion, SNMP agents can be easily installed and configured on different Linux servers. This will allow you to monitor your servers without the need for an agent, by using an On-Premise Poller.
Configuring SNMP agents on Linux servers can be a daunting task, but with this guide, it doesn't have to be. By following these simple steps, you'll have your servers monitoring in no time. And if you ever need help, our support team is more than happy to assist.
